Quite poor.
The art itself wasn't horrendous. It was substandard, but nothing to gripe about.
The sound, though fitting, was repetative and annoying.
The worst part about it was the animation. You used the same shots over and over, coupled with tweening, lots and lots of tweening that was very slow, and very revealing.
You say you did a bad job because "it was rushed" and you promise "a much better sequel"
Well, WHY was it rushed? It's not like Newgrounds has a deadline.
If you can do better, and you know you can do better, then do so, before submitting your flashes.
